Back to Contents INSTALLATION INSTRUCTIONS Use ropes to position the aerator in the desired location in the pond or lake. Anchor the ropes or secure them to the shoreline so that they are free of slack, but not tight. To prevent twisting of the unit due to motor torque, place the anchor at least 3 feet from the float for each foot of depth. (Example: a 6-foot-deep pond would require an anchor 18 feet horizontally from the float.
Back to Contents THREE-PHASE STARTUP PROCEDURE If a Kasco control panel is not provided, please refer to the following warnings: When inherent overheating protection is not provided, use with approved motor control that matches motor input in full load amperes with overload element(s) selected or adjusted in accordance with control instructions.
Back to Contents MAINTENANCE RECOMMENDATIONS UNDER NO CIRCUMSTANCES should anyone enter the water while equipment is operating. The following maintenance procedures can ensure many years of quality performance from your Kasco aerator and reduce the need for more costly repair work. Proper Installation Proper installation of Kasco equipment will include a power source with Ground Fault Interruption (GFI).
Back to Contents MAINTENANCE RECOMMENDATIONS (CONT.) Seal And Oil Replacement This is a sealed motor assembly, and seals will wear out over time (similar to brake pads on a car). Replacing the seals and changing the oil after three years may add longevity to the operation of the motor, saving you the cost of more expensive repairs.
Back to Contents TROUBLESHOOTING TIPS (CONT.) “My aerator hums, but will not start. When I spin the prop with a stick, it starts up.” (for single phase units only) This indicates a problem with the starting capacitor. Each Kasco aerator is equipped with a starting capacitor to get the unit going when it is first plugged in. If it is operating, but not spinning and can be started by spinning the prop with a stick, the starting capacitor needs to be replaced by an Authorized Repair Center.
